Hydrocracking of Di(1-Naphthyl)methane over Acid Solid Catalyst

Abstract

As a model reaction for coal liquefaction, the hydrocraking of di(1-naphthyl)methane (DNM) was investigated using acid solid catalyst (ASC) under different reaction conditions. The results show that acid solid catalyst selectively catalyzes DNM hydrocraking to give 1-methylnaphthalene and naphthalene, without hydrogenation product. The rate of DNM hydrocraking strongly depended on reaction temperature, reaction time and the catalyst feed, whereas effect of hydrogen pressure was not serious. The effects of acid solid catalyst is to make Car-Calk bond cleavage.
